The [s4s] board is a live 4chan board, shown exactly as posted. It may show pornography and other sexually explicit images, as well as offensive or disturbing posts. FunpostFM does not moderate it and cannot filter it.
The rest of FunpostFM does not need this — you can listen, chat and request without it.
The free On Air app is FunpostFM without the browser tab: a small radio that sits on your desktop, light enough for an old PC.
It updates itself. Windows may say “Windows protected your PC” the first time — click More info → Run anyway (the app isn’t code-signed yet). Open source: github.com/blastlaster/on-air — build it yourself on any Linux.
A tiny add-on: a FunpostFM button in your toolbar that keeps playing while you browse, shows what's on, and pings you when someone goes live.
Firefox version coming soon.
The radio in your pocket: plays with the screen off, song and art on the lock screen, and a ping when someone goes live.
Open the download on your phone and tap Install. Android will ask you to allow installs from your browser the first time. Android 5 or newer. Open source: github.com/blastlaster/funpostfm-android
